Description

Improved Air Bed Throttle Construction

The utility model relates to an improved throttle valve structure of an air cushion bed, which relates to a valve body structure.

With the increasing progress and development of medical science, various medical devices have also been continuously innovated and improved at the same time, in order to achieve a complementary effect with medical treatment. It is inconvenient for the body to turn over, and the long-term pressure on the part leads to the occurrence of decubitus disease caused by the proliferation of suppurative bacteria due to poor circulation. Only when the skin can be kept dry can it be possible to improve the symptoms of decubitus ulcers. Thereby, the generation of air mattress has just been arranged on the market, and its structure is roughly as shown in Figure 1, 2, generally is made up of an air mattress body 10, a control box 20 and two air intake pipes 30, and there is a The pump 40 and an adjusting device 50 repeatedly supply air by means of the adjusting device 50, and pass through the two air inlet pipes 30 to the three-dimensional strip tubes 101 of the air mattress body 10, so that the three-dimensional strip tubes 101 are in the state of expansion and contraction in the equal time difference (see Fig. 1, 2) so as to achieve the effect of massaging the patient, so that the compressed part of the patient can have alternate loose and tight pressure within a certain time difference, so as to achieve the purpose of keeping the part dry. This is the main function of an air mattress. In addition, as shown in Figure 3, wherein the regulating device 50 is made up of a motor 501, a spring 502, an air supply block 503 and a regulating valve 504, the air supply block 503 has an air supply pipe 5031 and two air intake pipes 5032, respectively connected to the air supply One air supply hole 5033 and two air intake holes 5034 on the top surface of the air block 50 are connected, and the air supply pipe 5031 is resisted by the two side plates 5011 above the motor 501, so that the air supply block 503 cannot rotate, and the regulating valve 504 is pressed in the supply position. Above the air block 503, its bottom is pushed upward by the spring 502, and inserted by a latch 505, so that there is no gap between the regulating valve 504 and the air supply block 503, and it is driven by the motor 501 to rotate slowly. In addition, the regulating valve 504 is The structure of the bottom surface has a central concave ring 5041 and several diversion grooves 5042 on the outside. The concave ring 5041 has a gap 5043 at an appropriate place to communicate with a diversion groove 5042, and a diversion groove 5042 is provided in the other diversion groove 5042. The through hole 5044 is used for air leakage.

Known from the structure of the regulating valve 504 above, its action principle is shown in Figures 4-7, when the notch 5043 of the regulating valve 504 turns to the left, the inflated diversion groove 5042 is not yet facing the second air inlet 5034, Make it not intake air (see Figure 4), when the regulating valve 504 is driven by the motor 501 to rotate to an air inlet 5034 facing the diversion groove 5042 full of gas, the air inlet 5034 can be inflated to the three-dimensional bar tube (See Figure 5), and then rotate to another air inlet 5034 when facing the through hole 5044, the corresponding three-dimensional bar tube can be deflated and shrink (see Figure 6), when one air inlet 5034 continues to inflate When it is saturated, continue to rotate until the air intake hole 5034 after the shrinkage is inflated, the other inflation hole 5034 is in the deflation (see Figure 7), and repeated actions like this constitute the expansion and contraction actions of the three-dimensional bar tubes apart. This repeated swelling and shrinking action acts as a massage. Yet because among the two air inlet holes 5034, one of them takes in air, while the other one is either inactive or deflated, and there is a certain time difference between one expansion and one contraction, that is, it is impossible to enter air at the same time. Therefore, this expansion The time difference between shrinking and shrinking is relatively long, which not only wastes electric energy, but also greatly reduces the effect of massage, so there is a need for improvement.

In view of the above reasons, the purpose of this utility model is to provide a new structure of air bed throttle valve which can shorten the time difference between expansion and contraction of three-dimensional tubes. It improves the massage effect and saves electricity.

The technical scheme of the utility model is realized in this way. There is a concave ring upward in the center of the bottom surface of the throttle valve, and a diversion groove is formed on the outside, and a gap is opened to the diversion groove on the outside at a suitable place of the concave ring. The bottom side of the throttle valve is an air supply block, which has an air supply pipe and two air intake pipes, and respectively corresponds to an air supply hole and two air intake holes; the outside of the bottom surface of the throttle valve has two diversion grooves of different lengths and short ones. The long diversion groove is connected with the two air intake holes that can cover the top surface of the air supply block at the same time, and the gap opened by the concave ring is connected with the long diversion groove, and a short groove is provided in the short diversion groove for venting use;

According to the above construction principle, when the throttle valve is rotated at a slow speed by a motor with a certain speed, one air intake hole can pre-supply the gas in the three-dimensional strip tube to a saturated state, and then the long diversion groove can also cover the other air intake hole at the same time At this time, the gas in the pre-inflated three-dimensional tube can support the separated three-dimensional tube, so as to save electric energy and reduce the time difference between the expansion and contraction of the separated three-dimensional tube, so as to improve the massage effect. The technical features of the present utility model will be further described according to the accompanying drawings and embodiments.

Embodiment: Figure 8 is a three-dimensional view of the regulating valve of the present invention. The utility model mainly refers to the improved structure of the throttle valve, and the utility model is illustrated through the action principle between the throttle valve 1 and the lower air supply block 2 . The air supply block 2 has an air supply pipe 21 and two air intake pipes 22, which respectively correspond to an air supply hole 23 and two air intake holes 24. There is a concave ring 11 upward in the center of the bottom surface of the throttle valve 1, and there are long and short rings on the outside. Different two diversion grooves 12, 13, a gap 111 is communicated with the diversion groove 12 at the appropriate place of the concave ring 11, and the long diversion groove 12 is the two air inlet holes that can cover the top surface of the air supply block 2 at the same time 24 communicated, in addition, the short diversion groove 13 offers a gap 131, for the purpose of venting. According to the action principle of the commonly used air bed control valve, see Figure 4-7 for details, and the action principle of the improved air bed control valve is shown in Figure 9-14, when the throttle valve 1 is driven by the motor and rotates at a certain slow speed When the long diversion groove 12 covers the two air inlets 24 (seeing Fig. 9 ) simultaneously, at this moment the two air inlet pipes 22 are inhaled and inflated simultaneously, and when continuing to rotate to the state of Fig. 10 . One of the air inlets 24 continues to take in air, while the other air inlet 24 deflates from the lack of groove 131, and then continues to rotate until the long diversion groove 12 covers the air inlet 24 (seeing figure 11) after the deflation, due to Another air intake hole 24 has continued to take in air and is saturated, so the air intake hole 24 in the air intake can be supported to shorten the inflation time, that is, the expansion and contraction time difference between the three-dimensional bar tubes is shortened, thereby saving electric energy and improving the The utilization rate of electric energy, when regulating valve 1 continues to rotate to the state of Fig. 12,13,14 again, then repeat aforesaid action principle, just its support and the exchange difference between the air intake hole 24 that is supported, namely form It is the same as the action of reverse support, so it can save electric energy and shorten the time difference between the expansion and contraction of the three-dimensional tubes, and improve the massage effect.

As can be seen from the above, the gas in the pre-inflated three-dimensional tubes of the present invention can support the separated three-dimensional tubes, so it can save electric energy, shorten the time difference between the expansion and contraction of the separated three-dimensional tubes, and increase the massage effect.
